The CodeJacked weblog details how to view and edit two different areas of your spreadsheet or document by splitting the screen.

A simple drag and drop can split your text document, Word document or more usefully, that gargantuan Excel spreadsheet in two for easier navigation. Also, they cover the most excellent Freeze Panes feature of Excel, which keeps a header row and column stuck in place while you scroll through your data. Apparently non MS Office apps have the split screen feature too, like TextPad 5. —Gina Trapani
